Detour is a location-aware app that provides guided audio tours. The app features audio that gives background, directions, and personal stories about places that users can listen to while walking around. Users can also sync the audio so that multiple people can experience any given “detour” at the same time. Andrew Mason, former CEO and founder of Groupon, is co-founder of Detour. Detour is scheduled to launch for the Bay Area later this year with a wider release in 2015.
